The present invention relates to the manufacture of knit goods, and theprimary object of the invention is to provide an improved method ofmaking these goods having certain advantages to be hereinafterdescribed, and an apparatus suitable for carrying out this method. v

The known kinds of hosiery produced mechanicall .along the lines of handknitting consist 0 thread interlacings linked together and continuallyconnected by rows in lines resembling an S or a double 8. However, allknown interlacings suffer from the drawback that, owing to breakage ofthethread and the like, runs are produced which continue to run in thelongitudinal direction of the goods. In order to prevent this droppingof loops, it has been proposed to employ worked-in wefts or reinforcingthreads or to cover the loops and thus prevent the formation of runs,but the goods treated in this manner lost part of their stretch as wellas other desirable qualities or could be used only for certain narrowlyrestricted purposes.

According to the present invention, the sinker loops are drawn out inthe known manner to form nooses which are then drawn through the loopsof their courses, engage the loops of the following course, and areworked out to looping knots. In this way, knit goods are producedwherein each loop is tied into a knot of the following course so thatdropped or broken loops cannot run.

he invention is illustrated in the accompanying drawings, in whichFigure 1 shows two finished courses; Fig. 2, goods according to Fig. 1with a second thread worked into each course and running partiallytogether with the ground thread in double-S form, each loop passingthrou h the knots formed by the ground thread; ig. 3, a diagram of theformation of a course according to Fig. 1; Fig. 4, a diagram of theformation of goods according to Fig. 2; and Figs. 5 to 9 show theformation of a plain course and a modification of the needles.

The manufacture of knotted goods requires special workin means for theformation of t e loops and coping knots. The needles 60 consist of twoparts n and d which can be movably arranged. The needles n per se andthe needles d per se can be grouped in bars or rows and these bars orrows moved independently of one another. The portion a of the needle isformed similarly to a spring needle or common hook and provided with agroove 2, the front being bent into a short hook it. Above these parts alooping needle 03 is disposed so that its front end is is somewhatburied in the groove 2 of the needle n and adapted to move forward andbackward in the longitudinal direction of the latter. With thesetwo-part needles looping for plain goods can be carried out also in theknown manner in the double-S style, the process of formin the coursesaccording to Fig. 1 being, or example, the following:

The lower or grooved parts n of the needles and the upper parts orlooping needles 5 are separately combined into bars, and both 7 groupscan be moved forward and backward independently of one another, theirworking method being illustrated partly in Figs.

5 to 9 and partly in the views 1 to 6 of Fig. 3. At first, a plaincourse similar to that produced in the known manner on a knitting frameis formed by driving out the lower needle parts n and the upper needleparts 03, which are originally in the position shown in view 1, Fig. 5,and Fig. 3, far enough to place 30 the loops lying in the needle hookI). over the upper needle parts d (Figs. 6 and 7 and Fig.

3, View 2). The thread a is then worked in by the covering needles 8 orsuitable jack sinkers, as shown in Figs. 7 and 4, views 7 s5 and 8,relative to the thread b.

After the thread a has been worked in, the needles n are moved backuntil the needle hook is disposed below the front part is of the upperneedle part d and the thread a enclosed in the hook h (Fig. 8).According to Fig. 9, the upper needle parts dare then moved slightly tothe front and, simultaneously, the needles n still more backwardly,whereupon the loops lying on the front part k of the upper needle partsd are pressed off and a lain course having double-S-like loops is eingformed in the known manner (F1 9 and view 1 of Fig. 3). The looping neeles d are then brought into basic positill (Z (View 5, 3).

tion (view 1, Fig. 3) and then, together with the needles n, driven outin the manner described until the loops formed are placed over the frontarts is of the looping needles (Z (View 2, 3) The lower needles n arethen moved back (View 3, Fig. 3) so that the sinker loops of the threada. can be lifted by the covering needles 3 or specially shaped jacksinkers and transferred laterally to the needles n without-beinghampered by the latter.

This step is shown diagrammatically in the views 1 to a of Fig. 3. Afterthe sinker loops have, for instance, been caught in the manner describedby the covering needle 8 and lifted laterally high enough to permit freemotion of the needles a under the covering needle 8, the needles n aredriven out again (View 4:, Fig. 3). The parts .9 are moved laterally ina somewhat oval path about the needles a so that the sinker loops of thethread a: rest on the needles n, as illustrated in views 7 and 8 of Fig.4 for the thread a. The members 8,.during their return course, are movedback far enough to be unable to interfere with the further steps in thework. The needles to are then moved back until the needle hooks hareplaced under the front portion In of the upper needle parts d and thecovered sinker loops are thus enclosed between the two needle parts 712and The needles or with the upper parts (Z are then moved backsimultaneously until the loops lying on the upper needle parts areknocked over so that a finished course has been formed according to Fig.1 (views 6 and 7, Fig. 3).

The loops thus formed form every time a looping knot, and these knotsare automat ically drawn together, when the goods are stretchedlongitudinally by a corresponding take-up. By working in a second threadinto each course (Figs. 2 and 4) the needle loops are reinforced, as thesecond thread Eb is made into a needle loop together with the thread a,while in the sinker as the two threads 11 and To run separately. n thisway the goods gain materially in durability and closeness. A secondthread 2') (Figs. 2 and 4) is worked in asfollows First the plain courseis formed with the thread a in the manner described, whereupontheneedles n are driven out again and the sinker loops transferred onthe latter. The needles 1:. remain in this driven out position, and thesecond thread I) is then worked in by the needles 8 (Fig. 4., View 7 Theviews 8, 9 and 10 of Fig. 4 show diagrammatically the working in of thesecond thread b. After the thread has been worked in the needles 1 aremoved back in the same manner as described so that the needle hooks hare placed first under the front portion In of the upper needle part andenclose the work-in thread 12 and the covered sinker loop, whereupon theneedles 'n and the upper needle parts d are moved back together untilthe loops on the front portion k of the upper needle part (Z are knockedover and a course is formed according to Fig. 2.

\Vhen using the needles and upper needle parts according to Figs. 5 to9, the needles 0 and (l are moved forward together from their initialposition (Fig. 5) until the loop resting on the needle 01 is placed overthe groove of the needle n, as shown in Fig. 6. The upper needles (Z arethen moved back so as to place the loop resting on the needle or on thefront portion 7a of the needle 71, whereupon the thread is prepared bythe sinkers p for a new loop, as indicated in Fig. 7. The needle or ismoved back after the thread has been sunk so that the thread loop isdrawn through the mesh resting on the front portion A: of the upperneedle (Z, the sinker being moved so high that the sunk thread loop isreleased. as illustrated in Fig. 8. According to Fig. 9, the needle (Iis then moved forward until the loop resting on its front portion 7a isreleased and a plain loop has been formed. The further steps leading tothe knotting of the loops are the same as described in con nection withFigs. 3 and 4.

The Working process is repeated in all courses formed one after anotheras in hosiery frames or knitting machines. Goods made under thisprocesscan be worked in a great variety of gauges and loop sizes, according tothe arrangement and type of needles used, and may be employed for allknown kinds of knit goods as well as for various other articles forwhich the known kinds of knit goods were not suited owing to the runningof broken or dropped loops.

I claim 2- 1. Method of manufacturing run-proof fabric which consists incausing a plain course to he formed by two-part superimposed needles,transferringthe needle loops from a lower grooved needle to an upperlooping needle, transferring the sinker loops of the said course, bymeans of covering needles, on the emptied lower grooved needles Lot andknocking the mesh loops held by the upper looping needles over thecovered sinker loops, the nooses formed from the sinker loops remainingas needle loops in the lower grooved needles.

2. Method of manufacturing knit goods of the kind described whichconsists in transferring the sinker loops of the first thread on thelower grooved needles, driving the latter out until a second thread canbe sunk thereon and knocking the needle loops of the first thread heldin the upper looping needles over the covered sinker loops of the firstthread and the sunk second thread, the nooses drawn from the sinkerloops of the first thread remaining together with the sunk second threadas needle loops in the lower grooved needles.

3. Apparatus for manufacturing knit I goods of the type mentioned andcarrying out the process described comprising in combination two-partsuperimposed needles arran ed in two groups and movable covering neeles, both needle groups being separately movable, the lower part of thetwo-part needles being provided with a groove and hook and the upperparts with a'gripper-like front portion to transfer the loops of thelower needle parts to the upper ones.

4. Run proof mesh goods knitted and knotted from.at-least one workingthread, having a. second mesh loop passed through the needle meshesthereof which is taken from the adjacent sinker loop, said sinker loopsbeing laterally ofi'set and then drawn through the needle meshesresulting in knotlike loops.

5. Run-proof knitted and knotted mesh goods made from two workingthreads wherein a knot-like mesh loop is formed from the first thread, aloop being formed from adjacent sinker meshes, and the second workingthread runs through the said knot-like ,mesh loop of the first thread,to form a second, larger mesh loop, so that the needle mesh of thesecond thread is tied-in, in the mesh knot of the first threadformed'thereon and lies the sinker loops separate from the first threaIn testimony whereof I afiix my signature.
